Have you tried calibrating your screen?

Hold down alt/option + one of the brightnessbuttons to open system preferences for your screen and then click the Color-tab. There you have a lot of profiles that you can try and you can also calibrate the screen from here (create a new profile).

Calibrating won't fix it 100% (movies acctually look better on windows) but it will fix it good enough so that you hardly can tell the difference between windows and mac unless the computers are next to each other.

This was of course meant to be a reply to this thread
